mDNS: restriction to a single interface (#6224)

Browse Source 
Default interface is STA (or AP if available and STA is unavailable).
An interface can also be specified in ::begin() by its IP address.
MDNS will not cross interfaces (there is currently no notion of "bridged interfaces")

Multiple instances should be working, this is not tested in this commit.
